Focusrite interfaces have good drivers and generally sound good.
If you can go a little higher, I would go for their Clarett series of interfaces, which sound very good. Something like the Clarett 2Pre would work well and you can sometimes find demo units right around $300. If you go that way, just make sure you get the USB version as they make Thunderbolt versions too.

used Focusrite Scarlett (or b-stock) with as much IO as you need. I have the 3rd Gen 18i20 I bought as B-stock from Focusrite. Headphone outputs happily drive a pair of AKG K702's, so you should be fine.
